Molecularly imprinted polymers are crosslinked polymerization product based on the interaction between template molecules and functional monomers. The separation between template molecules and competitive molecules are achieved through high-performance liquid chromatography (HPLC) by utilizing the specific recognition moieties of imprinted cavity. A summary is provided about the recent progress of molecularly imprinted HPLC column, focusing on their synthetic approaches and characterization methods. The influential parameters affecting the separation efficiency of molecular imprinting-based HPLC, e.g. the choice of template molecules, the surface structure of packing materials and chromatographic conditions, are also discussed. Finally, the prospects and deficiencies of molecular imprinting-based chromatography in separation of drugs are addressed.
